 DETAILED DESCRIPTION

One or more specific embodiments will be described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

When introducing elements of various embodiments of the present invention, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.

Embodiments of the present disclosure may apply to a variety of eyewear, including sports-oriented eyewear such as swim goggles, sunglasses, ski goggles, motorcycle goggles, helmet visors, and so on. In certain embodiments, a minimally intrusive display system (MIDS) may be included in the eyewear, suitable for providing visual indications and feedback of ongoing user and/or sensor activities, as further described below. The MIDS may include a small form factor, such as 50×50 mm square, or less, that enables the user to more quickly identify useful information on a display while maintaining situational awareness. That is, the user may glance at information provided via a display included in the MIDS while still maintaining a field of view suitable for easy visualization of the surrounding environment.

In certain embodiments, the MIDS may be removable and replaceable. For example, the user may toolessly remove the MIDS from a swim google and then place the MIDS into a set of sunglasses for use in a non-swimming activity. Indeed, the MIDS may be toolessly interchangeable between various types of eyewear. Additionally, the MIDS may include one or more processors that may interface with one or more sensors (internal sensors, external sensors) to derive certain performance metrics and/or feedback related to the user's activity.

For example, when swimming, feedback may be provided related to starts, turns, kicks, lap counts, breathing, speed, swim direction, and so on. When running, feedback may include speed, kick cadence, arm cadence, gait type, gait length, and the like. When bicycling, the feedback may include speed, pedaling cadence, power output, bicycle inclination, and so forth. Feedback for other activities is described below. The MIDS may communicate with external computing devices (e.g., cell phones, tablets, notebooks, cloud-based systems, smart watches, and the like) as well as with other MIDS to provide, for example, for virtual racing, improved coaching, sports social networking, and so on. By providing for the minimally intrusive techniques described herein, users may experience enhanced sports activities while improving their individual performance.

Turning now to FIG. 1, the figure is a block diagram of an embodiment of a sport-oriented system 10 which may include one or more minimally intrusive display systems (MIDS) 12. As mentioned earlier, the MIDS 12 may be disposed in a variety of eyewear, such as swim goggles 14, sunglasses 16, ski goggles 18, and/or helmet visors 20. In certain embodiments, a MIDS 12 may be permanently attached to each of the goggles 14, sunglasses 16, ski goggles 18, and/or helmet visors 20. In other embodiments, the MIDS 12 may be removable and replaceable. For example, the MIDS 12 may be toolessly removed from the swim goggles 14 and then toolessly attached to the sunglasses 16, the goggles 18, the visor 20, and/or to another swim google 14. It is also to be understood that the list of eyewear shown is not limiting, and that other eyewear may be used with the MIDS 12, including prescription sports glasses, shooting glasses, automobile driving glasses, and so on.

In use, the MIDS 12 may provide for a minimally intrusive information display suitable for presenting a variety of information related to the activity being performed by wearer, such as swimming 22, bicycling 24, running 26, motorcycling 28, skiing 30, and so on. Accordingly, the MIDS 12 may include one or more internal sensors described in more detail below, suitable providing data correlative with the activity being performed. The MIDS 12 may additionally interface with a variety of external sensors 32 that may be worn by the user and/or disposed in certain equipment, suitable for providing data also correlative with the activity being performed.

The external sensors 32 may include accelerometers, gyroscopic sensors, speed sensors, location sensors (e.g., GPS, GLONASS systems), ambient temperature sensors, humidity sensors, altitude sensors, magnetometric sensors (e.g., compass systems), wind sensors (e.g., wind speed, wind direction), barometric pressure sensors, biometric sensors (e.g., pulse oximeters, body temperature sensors, electrocardiogram sensors, health informatics sensors [e.g., ISO/IEEE 11073 sensors]), and the like, that may be communicatively coupled to one or more of the MIDS 12. For example, the MIDS 12 may include certain wireless systems, such as Wi-Fi (e.g., Institute of Electrical and Electronics Engineers [IEEE] 802.11X), cellular systems (e.g., high speed packet access [HSPA], HSPA+, long term evolution [LTE], WiMax), near field communications (NFC) systems, Bluetooth systems, personal area networks (PANs), Zigbee systems, Z-wave systems, wireless mesh systems, and the like, and so on, suitable for wirelessly communicating with the sensors 32. It is to be noted that the sensors 32 may be included in other systems, such as smart watches, smart bands, pedometers, wearable heart monitors, disposed in vehicles, and so on, which include wireless communications.

The MIDS 12 may additionally or alternatively interface with mobile devices 34 (e.g., cell phones, tablets, notebooks, laptops), a cloud-based system 36, and/or other external computing system 37. For example, the mobile devices 34, cloud-based system 36, and/or external computing systems 37 may be used to configure settings of the MIDS 12 as well as to communicate data during activities, such as during the sports activities 22, 24, 26, 28, and/or 30. In certain embodiments, the communications may be one-way communications. For example, a tablet 34 carried by a swimming coach (e.g., poolside coach) may receive information (e.g., lap count, inhalation/exhalation patterns, head movement, body roll, kick pattern, speed, etc.) incoming from the MIDS 12 and/or derive the information via data incoming from the MIDS 12. The information may then be used to give feedback to the wearer of the MIDS 12 during swimming activities 22.

In other embodiments, MIDS 12 communications may be two-way communications. In such embodiments, the wearer may receive information from external systems, such as the mobile devices 34, the cloud-based system 36, and/or other external computing systems 37 (e.g., computing systems including workstations, desktops, smart TVs, etc.) for configuration of the MIDS 12 and/or to provide feedback on the activity being performed by the wearer. For example, virtual coaching and training, gaming, social networking, and the like, may be provided via two-way communication, as described in more detail below.

It may be beneficial to illustrate example views of the MIDS 12 disposed on an eyewear system. Accordingly and turning now to FIG. 2A, the figure is a front perspective view of an example MIDS 12 disposed on the swim goggles 14. In the depicted embodiment, the MIDS 12 is disposed on a left lens 40 of the swim goggles 14. However, in other embodiments the MIDS 12 may be disposed on a right lens 42 of the swim goggles 14. In yet other embodiments, the MIDS 12 may be disposable in either the left lens 40 or the right lens 40 based on the user's preference. For example, the MIDS 12 (or the entire left lens 40) may be toolessly removed and repositioned onto the right lens 42 (or right side) of the swim goggle 14. Indeed, in some embodiments the MIDS 12 may be removed by hand and then placed onto another type of eyewear (e.g., sunglasses 16, ski goggles 18, helmet visors 20), another set of swim goggles 14, and/or to the other side or lens of the swim goggles 14.

FIG. 2B is a front perspective view showing an embodiment of the swim goggles 14 with the MIDS 12 removed. More specifically, the figure illustrates an opening 44 suitable for deploying the MIDS 12 in situ. For example, the user may carry various swim goggles 14 with different opacities, goggles 14 for outdoor swimming, customizable goggles 14 (e.g., Swedish swim goggles), prescription goggles 14, and so on, and then easily insert the MIDS 12 into the opening 44 based on type of event, ambient conditions, and so forth. In certain embodiments, the MIDS 12 may mechanically couple with the lens 40 via an interference fit between edges of the opening 44 and an outer shell of the MIDS 12. Other coupling techniques may include tongue and groove fastening techniques, magnetic fasteners, mechanical latches, catches, and so on.

In use, the MIDS 12 may provide for an improved field of view even with the MIDS 12 in place, as shown in FIG. 2C. More specifically, FIG. 2C is a rear perspective view illustrating an embodiment of the MIDS 12 disposed in the lens 44. As illustrated, the MIDS 12 may occlude only a small section of the lens 44, while leaving a larger section 46 unobstructed. Accordingly, the wearer may have and improved situational awareness and field of view when compared to larger display systems, useful in sports activities. It is to be note that while FIGS. 2A-2C depict the MIDS 12 using swim goggles 14 for context, the MIDS 12 may be disposed in openings 44 found in other eyewear, such as the sunglasses 16, the ski goggles 18, and/or the helmet visors 20.

FIG. 3 is a system architecture block diagram of an embodiment of the MIDS 12. As depicted, the MIDS 12 may include one or more processors 50 and memory 52. The processor 50 may include “general-purpose” microprocessors, special-purpose microprocessors, application specific integrated circuits (ASICS), a reduced instruction set (RISC) processors, field programmable arrays (FPGAs), or some combination thereof. The memory 52 may include a volatile memory, such as random access memory (RAM), and/or a nonvolatile memory, such as ROM. The memory 52 may store a variety of information and may be used for various purposes. For example, the memory 52 may store processor-executable instructions (e.g., firmware or software) for the processor(s) 50 to execute. The MIDS 12 may also include a storage device 54. The storage device 54 may include a hard drive, a flash drive, a solid state storage medium, or combination thereof, suitable for storing digital data. Power for the MIDS 12 and its systems may be provided via a power supply system 56, which may include one or more rechargeable batteries chargeable via induction charging techniques and/or wired charging techniques.

In use, visual data (e.g., text, icons, images) may be provided via a display system 58. The display system 58 may include a low power micro display system (e.g., micro LED display) having, for example, a total size of 40 mm by 40 mm, 30 mm by 30 mm, 20 mm by 20 mm, 10 mm by 10 mm, or less. The display system 58 may be positioned in peripherally to the eye as shown in FIGS. 2A-2C, such that the display system 58 does not disturb forward vision. Peripheral positioning may include the corner of the eye (left or right), but it may also include the bottom or top of the eye. When placed at the top or bottom positions, two MIDS 12 may be used so that two display systems 58 are placed in both eyes, creating binocular vision.

When positioned as described, if the athlete or wearer is not looking at the display system 58 then the athlete doesn't see the information and is not disturbed by the MIDS 12. In other words the display system 58 may appear invisible unless looked at directly. Additionally, by having a direct display system 58, as opposed to an indirect display system having prisms, mirrors, projectors, and so forth, the MIDS 10 may be manufactured in a smaller and more reliable form factor, suitable for providing useful information while also providing for situational awareness and a more open field of view.

In addition to or alternative to LED displays, the display system 58 may include one or more LED lights. Light feedback may be advantageous because it may not break exercise concentration or require deeper processing. Simple color lights may be used to indicate performance. For example, green would indicate good performance in swim turns, swim stroke, swim kick cadence, bike speed, run speed, bike cadence, run cadence, ski turns, motorcycle lean, and so on. Red may indicate when performance is not as desired. Accordingly, the MIDS 10 may be capable of filling the eyewear with colored light to provide feedback to the wearer.

Further, an input/output (I/O) system 60 may provide for other output modalities haptic output, and/or audio output. Haptic output may include force feedback such as “tapping” motions. Audio output may be provided via bone conduction, via wireless techniques (e.g., Bluetooth Advanced Audio Distribution Profile [A2DP], aptX), and/or via a waterproof audio port. Audio feedback may indicate a “good” noise when performance is desired, such as a chime, and a “bad” noise when performance is not as desired, such as a buzzer. Audio feedback may additionally or alternatively include a metronome-like sound played to help improve stroke count when swimming, cadence when biking and/or running, to keep track of elapsed time, and so on. The sound or “tappings” may also be set to operate adaptively by increasing/decreasing swimming stroke rate, bicycling/running cadence, skiing turns, and the like, by a fraction; and therefore slowly improving stroke rate, cadence, turning, and the like, without forcing the wearer to coarsely jump between rates. Audio output may also include voice coaching, music playing, and so on.

Input may be received via the I/O system 60, for example, via one or more buttons, and/or via touch sensors. The touch sensors may be suitable for receiving gesture inputs, such as swiping, tapping, pressing, holding, and so on. Accordingly, the user may switch modes, turn displays on and off, and so on. A wireless system 62 may also be included in the MIDS 12. As mentioned earlier, the wireless system 62 may include systems such as Wi-Fi (e.g., IEEE 802.11X), cellular systems (e.g., HSPA, HSPA+, long term evolution LTE, WiMax), near field communications (NFC) systems, Bluetooth systems including low power Bluetooth systems, personal area networks (PANs), Zigbee systems, Z-wave systems, wireless mesh systems, and the like, and so on, suitable for wirelessly communicating with other systems, such as the mobile system 34, the cloud-based system 36, and/or other external computing systems 37. Internal sensors 64 may include accelerometers, gyroscopic sensors, temperature sensors, ambient temperature sensors, humidity sensors, altitude sensors, magnetometric sensors (e.g., compass systems), barometric pressure sensors, biometric sensors (e.g., pulse oximeters, body temperature sensors, electrocardiogram sensors, health informatics sensors [e.g., ISO/IEEE 11073 sensors]), and the like.

A global positioning system (GPS) and/or GLONASS system 66 may also be included in the MIDS 12. The GPS system 66 may be used to provide for the MIDS 12 position of relative to a fixed global coordinate system, a fixed local coordinate system (e.g., indoor GPS), or a combination thereof. The GPS 66 may additionally use real time kinematic (RTK) techniques to enhance positioning accuracy. An inertial measurement unit (IMU) 68 may also be included, which may include one or more sensors, such as specific force sensors, angular rate sensors, accelerometers, gyroscopes, and/or magnetic field change sensors that may provide for the inertial measurements as the MIDS 10 moves. The IMU 68 may be used to provide for one or more degrees of freedom (DOF) measurements correlative with certain performance during activities 22, 24, 26, 28, 30 when the MIDS 12 is disposed on the wearer, as described in more detail with respect to FIG. 4. By placing a small heads up display in the MIDS 12 and/or by using audio feedback techniques as described, the athlete doesn't interrupt exercise cadence to consume information, unlike when using wrist-based devices. With wrist-based devices, the athlete typically has to stop swimming to see information or otherwise disrupt the their activity such as by changing running cadence to allow the wrist to be raised and viewed, disrupting cycling pedaling cadence to examine a wrist or handlebar display.

FIG. 4 depicts an embodiment of a process 78 suitable for deriving certain performance baselines for wearers of the MIDS 12. The process 78 or certain steps of the process 78 may be implemented as computer-executable instructions executed via the processor(s) 50, the mobile device 34, the cloud-based system 36, and/or other external computing systems 37. It to be understood that the process 78 may include steps that are optional, and that the steps may be performed in other order than the one shown.

In the depicted embodiment, the MIDS 12 is shown disposed in the swim goggles 14 during swimming activities 22. As mentioned above, the IMU system 68 may include sensors (e.g., as specific force sensors, angular rate sensors, accelerometers, gyroscopes, and/or magnetic field change sensors) that may be used to sense multiple degrees of freedom of the wearer's head. In the illustrated embodiment, 6 degrees of freedom are provided by the IMU system 68, including pitch 80, roll 82, yaw 84, up 86, down 88, left 90, right, 92, forward 94, and back 96. Accordingly, the MIDS 12 may receive and log (block 98) real-time data representative of the 6 degrees of freedom as the user undergoes an activity, such as swimming 22, resulting in logged data 100. The logged data 100 may also include data from the internal sensors 64 and/or the external sensors 32.

Certain techniques, such as a machine learning system 102, may be used to process the logged data 100 to recognize (block 104) the wearer's activity (e.g., activities 22, 24, 26, 28, 30) and the wearer's performance during the activity. For example, logged data 100 may be tagged as swim data, and the machine learning system 102 trained to recognize that the wearer was swimming. Likewise, the machine learning system may be trained to recognize any one of the activities 24, 26, 28, 30. The machine learning system 102 may then be used to derive (block 106) certain baselines 108 based on the activity. For example, for swimming 22, starts (e.g., block starts, outdoor swim starts), turns (e.g., flip turns, side turns, buoy turns), splits and sets, times, strokes (e.g., freestyle, breaststroke, butterfly, backstroke, sidestroke), kicking cadence, breathing patterns, head position during the swim, and so on, may be baselined. For example, a professional athlete may be “recorded” (e.g., used to provide the logged data 100) during swim turns and the machine learning system 102 may then train a neural network to recognize a “good” turn. This trained network then may become one of the baselines 108. The baseline(s) 108 may also be provided by statistical analysis. For example, the logged data 100 may be analyzed to derive medians, averages, ranges, which may then act as the baseline(s) 108. Accordingly, deviations, such as standard deviations, percentile deviations, quartile deviations, and so on, from the medians, averages, and/or ranges, may be outside of the baseline(s) 108. In this manner, baselines may be derived for “good” starts, strokes, kicking, breathing, head position, and so on.

Each activity 22, 24, 26, 28, 30 may be similarly processed to derive “good” (and “bad”) baselines 108. For example, for bicycling 24, the baselines 108 may include recordings of flat terrain cadence, hill climbing cadence, sprinting, aero tuck head positioning, drafting, hill descent positioning, gear changes, and so on. For running 26 the baselines 108 may include flat terrain cadence, hill climbing cadence, hill descent cadence, arm rotation, foot landings, and so on. For motorcycle riding 28 the baselines 108 may include leaning on curved road sections, accelerating, braking (front wheel braking, rear wheel braking), and the like. For skiing 30 the baselines 108 may include parallel turning, edging, carving, cadence based on incline, and so on. The baselines 108 may also include biometrics, for example when biometric sensors 32 are used. The biometrics may include heart rate, body temperature, peripheral capillary oxygen saturation (e.g., SpO2 provided via pulse oximetry sensors), calories burned, and the like.

The aforementioned baselines 108 are for example only and are non-limiting, as any number of baselines may be created based on a “recording” of a wearer performing some activity as well as manually through analysis of the logged data 100. It is to be noted that the baselines 108 are not restricted to logged data 100 recorded by professional athletes but may be derived for any user of the MIDS 12. For example, an amateur athlete may record” him or herself and then provide the recordings (e.g., logged data 100) to a coaching system for evaluation and/or to keep a record of progress, as further described below. The baselines 108 may also be used to analyze, in real-time, performance of the wearer of the MIDS 12 to provide feedback as to how to improve performance.

FIG. 5 depicts an embodiment of a process 120 suitable for deriving certain performance metrics and/or feedback for wearers of the MIDS 12. The process 120 or certain steps of the process 120 may be implemented as computer-executable instructions executed via the processor(s) 50, the mobile device 34, the cloud-based system 36, and/or other external computing systems 37. It to be understood that the process 120 may include steps that are optional, and that the steps may be performed in other order than the one shown.

In the depicted embodiment, the wearer of the MIDS 12 may be performing the swimming activity 22 while training, competing, or simply for enjoyment of the activity 22. The MIDS 12 may enhance the activity 22 by providing for certain feedback. For example, as the wearer swims, the process 120 may receive (block 122) data 124, such as the degrees of freedom via the IMU system 68, as well as other sensed data from the sensors 32, 64. In certain embodiments, the data may be processed to derive (block 126) certain metrics 128. Deriving (block 126) the metrics 128 may include deriving the activity being performed, e.g., activity 22, 24, 26, 28, 30. Accordingly, the metrics 128 may be correlative with the activity being performed. For example, for swimming 22, the metrics may include speed, direction of travel, compass heading and/or location (for open water swimming), elapsed time, splits and sets, number of laps, type of stroke used, breathing metrics, head position metrics, kicking cadence, stroke cadence, body roll metrics, and so on.

For bicycling 24, the metrics 128 may include speed, direction of travel, compass heading and/or location, elapsed time, elapsed distance, as well as data gathered via external sensors 32 such as crankarm RPM (e.g., crankarm cadence), power output at the pedals (in Watts), current gear selected, bike odometer, and so on. For running 26 the metrics 128 may include speed, direction of travel, compass heading and/or location, elapsed time, elapsed distance, running cadence, arm cadence, foot placement, kicking cadence, and so on. For motorcycling 28 the activity metrics may include speed, direction of travel, compass heading and/or location, elapsed time, elapsed distance, leaning metrics, braking metrics, acceleration metrics, as well as data gathered via external sensors 32 such as MPG, engine RPM, odometer, gas tank level, coolant level, oil level, remaining range, error codes, and so on. For skiing 32 the metrics 128 may include speed, direction of travel, compass heading and/or location, elapsed time, elapsed distance, parallel turning metrics, edging metrics, carving metrics, cadence based on incline metrics, and so on.

The metrics 128 may also include biometrics, for example when biometric sensors 32 are used. The biometrics may include heart rate, body temperature, peripheral capillary oxygen saturation (e.g., SpO2 provided via pulse oximetry sensors), calories burned, and the like. The metrics 128 may also include ambient metrics such as temperature, ambient pressure, altitude, humidity, and the like. Additionally, the metrics 128 may include GPS/GLONASS metrics such as current position and compass heading. Any one or more of metrics 128 may then be displayed (block 130), for example via the display system 58 and/or I/O system 60. As described earlier, the display system 58 may be positioned so that if the athlete or wearer is not looking at the display system 58 then the athlete doesn't see the information and is not disturbed by the MIDS 12. That is, the display system 58 may appear invisible unless looked at directly. In certain embodiments, the wearer may configure the MIDS 12 to create a user profile that may customize, for example, the set of metrics 128 to display for each of the activities 22, 24, 26, 28, 30.

The process 120 may also compare (block 132) the metrics 128 to the previously derived baseline(s) 108 to derive a quality measure 134. For example, a swim turn may include various metrics 128 such as head position at various points of the turn, speed of the head, leg positions/kicks, and/or body positions (via sensors 32 disposed on the body), through the turn. The metrics 128 may be compared (block 132) to metrics in the baseline(s) 108 to derive the quality measure 134. The comparison may include comparison by range (e.g., if the observed metric 128 is inside a range found in the baseline(s) 108), statistical comparisons (e.g., inside of a percentile, quartile, via standard deviation techniques, ANOVA techniques, MANOVA techniques, etc.), and/or AI comparisons (e.g., when the baseline(s) 108 include pattern recognition via neural networks, state vector machines, expert systems, fuzzy logic, and so on). The quality measure may be a binary measure, e.g., “good” and “bad”, and/or a number such as a number between 1-10, 1-100, and the like, for example, denoting how close the metrics 128 are to the baseline(s) 108. Example quality measures for swimming include but are not limited to a swim turn quality measure, a kicking cadence quality measure, a body roll quality measure, a stroke performance quality measure, a head position quality measure, and so on. The quality measure 134 may then be displayed via the display system 58 and/or the I/O system 60. By providing for feedback during the performance of activities in a minimally intrusive manner, the MIDS 12 may enable improved training, competition, and an increased enjoyment of the activities.

FIG. 6 is a block diagram illustrates an embodiment of multiple systems, including a coaching/training system 150, a gaming system 152, an in-competition system 154, and a social networking system 156 that may interface with the MIDS 12 while worn by users. The systems 150, 152, 154, 156 may include software systems executable via the MIDS 12, the mobile device 34, the cloud-based system 36, and/or other external computing systems 37.

In the depicted embodiment, the coaching/training system 150 may receive, for example, the metrics 128 and/or data representative of the metrics 128 in real-time and/or offline and then provide for a repository of the MIDS 12 data as well as for feedback. For example, wearers may track daily, weekly, monthly progress by logging into the coaching/training system and visualizing or comparing, via a tablet, cell phone, computer display, and the like, training and/or competition metrics 128 as well as training and/or competition quality measures 134 throughout a desired time period (e.g., day week, month. The coaching/training system 150 may also provide feedback to improve performance. For example, the coaching/training system 150 may use AI, statistical, and/or human based analysis to analyze the metrics 128 and/or quality measures 134 and provide feedback on how to improve swim turns (e.g., suggestion on when to start a turn, speed of the turn, improvements to head position, improvements to body tuck, when to leg push, and so on). Similarly, for swimming 22, suggestions for stroke improvements, kicking cadence, breathing and breathing cadence, drafting, when to “attack” during competition, may be provided.

For running 24, the coaching/training system 150 may provide feedback such as suggestions on cadence, kicking, arm movement, pacing for distance, head lean, and so on. For bicycling 26, the coaching/training system 150 may provide feedback such as suggestions on speed, RPMs, when to get off the saddle, pedaling cadence, head position, gear shifting, drafting, and so on. For motorcycling 28, the coaching/training system 150 may provide feedback such as suggestions on leaning, gear changes, acceleration, braking, head position, and so on. For skiing 30, the coaching/training system 150 may provide feedback such as suggestions on where to look, parallel turning, edging, carving, stopping (e.g., v-stop, side stop), foot rotation, and so forth.

The coaching/training system 150 may also enable for remote or virtual coaching. For example, a human coach 158 may be located at a different geographic location from wearer 160 and from wearer 162. By using the coaching/training system 150, for example via a software application (e.g., app) 164, the coach 158 may receive real-time feedback, metrics 128, and/or quality measures 134 while the wearers 160, 162 are performing an activity, e.g., swimming 22. The coach 158 may then provide for recommendations on technique, changes to certain techniques, new training schedules, and so on. In some embodiments, the coach's 158 feedback may be displayed in the MIDS 12 (e.g., via display system 58, I/O system 60) or provided as audio.

The gaming system 150 may provide for virtual racing against a virtual athlete 166 as well as against wearers 160 and 162 disposed in different geographic locations. The virtual athlete 166 may be an athlete that has been previously “recorded” with the techniques described herein. For example, the virtual athlete 166 may have been recorded in an Olympic size pool but then processed by the gaming system 150 to compete in open ocean swimming, in other pool lengths, and so on. Further, the virtual athlete 166 may be a previous recording from any wearer, including wearers 160, 162. The gaming system 150 may further process the wearer's recording to extrapolate a different type of swim, e.g., open ocean swim, during a virtual race. Further, the virtual athlete may be a fictional athlete created for virtual competition (e.g., aquaman). By connecting wearers 160, 162, at different locations, and by providing for one or more virtual competitors 166, the gaming system 150 may enable competitions across disparate geographic regions and with a broad category of competitors, including virtual athletes.

The in-competition system 154 may be used during actual competitions of the activities 22, 24, 26, 28, 30. Each competition may include a different set of rules as to what functionality the MIDS 12 may provide during the competition. For example, coaching functionality may be disabled. Accordingly, the MIDS 12 may receive a competition template disabling and/or enabling certain MIDS 12 functionality during the competition. The MIDS 12 may also be used in lieu of or in addition to competition smart tags, such as by tracking arrival at certain designated spots, providing for GPS tracking of competitors, providing for health information of competitors (including providing data from external health sensors), and so on.

FIG. 6 also illustrates “hand-off” capabilities of the MIDS 12 during multi-sport events, such as biathlons, triathlons, relay sports, and so on. In the illustrated embodiment, once the wearer 162 may have previously set up two MIDS 12 for triathlon. One MIDS 12 may be disposed in swim goggles 14 and the second MIDS 12 may be disposed in sunglasses 16. Once the wearer 162 exits the water and removes the swim goggles 14, the removal motion may then trigger a transition portion 168. During the transition portion 168 certain information may be tracked, such as a first triathlon transition time clock, to record transition times between swim-bike portions. Once the wearer 162 dons the sunglasses 16, the MIDS 12 on the sunglasses 16 may then take over and provide information during a bicycling portion 170 of the event. Once the bicycling portion 170 is complete, the wearer 162 may use the I/O system 60 to direct the second MIDS 12 disposed in the sunglasses 16 to begin a second transition 172. The second MIDS 12 may then, for example, begin a second triathlon transition time clock to record transition times between bike-run portions. The second MIDS 12 may then provide the wearer 162 information during a run portion 174 of the event. Data captured during the transitions may then be submitted to the systems 150, 152, 154, and/or 156. Indeed, the coaching/training system 150, the gaming system 152, the in-competition system 154, and/or the social networking system 156 may support data storage and analysis of multi-sport or relay sport data, including transitions 168, 172.

The social networking system 156 may enable meetings, virtual events, and data sharing between various users of the MIDS 12, including amateur users of various levels, professional users, and/or coaches. For example, the social networking system 156 may enable the discovery of other uses of similar performance levels. The users may form networks for training, competition, and/or advice. For example, a network may be formed via the social networking system 156 for users interested in learning how to swim using the butterfly stroke. The social networking system 156 may then coordinate training meets, including virtual meets, coaching, and progress tracking amongst the group, virtual competitions for group members, creation of virtual awards and points earned, and so on. Coaches may sign up via the social networking system 156 and advertise their expertise. The coaches may then provide services via the coaching/training system 150 and the MIDS 12. The social networking system 156 may thus be communicatively coupled to the systems 150, 152, 154, to share data, to share functionality, and/or to provide for a single login into all systems 150, 152, 154, 156.

FIG. 7A and 7B illustrate embodiments of certain areas 200, 202 of the MIDS 12 that may include the display system 58. In the embodiment depicted in FIG. 7A, the areas 200 includes a LED pixel display 204 that is shown displaying text. More specifically, the display 204 is displaying a time 206, a minute separator 208, a lap counter 210, and a swim indicator 212. The time displayed is thus 2:00 minutes, with 15 laps counted while still swimming. The display 204 may be small in size, such as between 10 mm by 10 mm to 40 mm by 40 mm or less. Accordingly, the display 204 may be disposed in a corner of eyewear to provide for a minimally intrusive display.

Further, FIG. 7A illustrates that the display system 58 may include a LED light 214, such as a multi-color LED. In use, the LED light 214 may be turned on at one or more colors based on the metrics 128 and/or the quality measure 134 derived during the various activities 22, 24, 26, 28, 30. For example, the color red may be displayed if certain metrics 128 and/or quality measures 134 are below a certain threshold, and the color green may be displayed if the metrics 128 and/or quality measures 134 are above the threshold. The light 214 and/or display 204 may be customizable by the wearer. For example, the wearer may select which of the various metrics 128 to be displayed as text, such as but not limited to speed, elapsed distance, elapsed time, splits, sets, laps counted, kicking cadence, and stroke cadence. The quality measures 134 may also be customized by the wearer to select which ones are be displayed as text, such as “good turn”, “bad turn”, “slow kick”, “fast kick”, and so on.

FIG. 7B illustrates the use of icons on the display 204. That is, in addition to text, icons may also be displayed. For example, the illustrated embodiments show an up arrow 216, a down arrow 218, a left arrow 220, and a right arrow 222. The arrows 216, 218, 220, 222 may be used to provide directions during certain activities as well as to provide feedback. For example, the up arrow 216 may indicate that a swimmer is swimming towards a desired direction during an outdoor swim, and when the swimmer strays form the desired direction, the left arrow 220 may be flashed to indicate to the swimmer to swim towards his or her left side to get back to the desired swim direction. Likewise, the right arrow 22 may be flashed to indicate to the swimmer to swim towards his or her right side to get back to the desired swim direction.

The up arrow 216 may also be displayed, akin to a “thumbs up”, when a desired metric 128 and/or performance measure 134 is reached, the down arrow 218 may be displayed if the metric 128 and/or performance measure 134 is not reached. It is to be noted that other icons may be used, such as emoji (e.g., thumbs up icon, thumbs down icon, smiley face, sad face, and so on).

FIG. 8 is a schematic view of an embodiment of a double mirrored display system 250 that may be included in the display system 58. The double mirrored display system 250 may use two mirrors 252 and 254 (e.g., “folded” mirrors) to increase a track length of the double mirrored display system 250, thus providing for a suitable presentation of visual information in a more compact package. That is, the mirrors 252 and 254 enable light to travel from a projective display system 256 into an eye entrance 258 with travel length or track length longer than directly projecting the light into the eye entrance 258. Accordingly, an improved view of data projected via the projective display system 256 may be provided.

The projective display system 256 (e.g., LCD, laser, etc.), which may be disposed on a printed circuit board (PCB). As light exits the projective display system 256, it then reflects off of the first mirror 252. The first mirror 252 may include a curvature, thus acting as a first lens suitable for magnifying the projected images. The light may then reflect off of the second mirror 254. The second mirror 254 may include a slight curvature to act as a slight correcting lens. The light may then be further enhanced via a normal aspheric lens surface 260. In some embodiments, the aspheric lens surface 260 may include a surface profile designed to reduce or to eliminate spherical and optical aberrations. In one embodiment, all components of the double mirrored display system 250 (e.g., the mirrors 252, 254, surface 260) may be manufactured as a single piece, for example, a piece molded in polymethyl methacrylate (PMMA), Polycarbonate, Zeonex, and so on. Additionally, the double mirrored display system 250, and indeed a variety of displays incorporated in the display system 58, may be disposed so that during the activity (e.g., activities, 22, 24, 26, 28, 30) the user may have a clear view of the activity and then with a slight movement of the eye, see information displayed via the display system 58 as further described below with respect to FIGS. 9-12.

FIG. 9 is a schematic top view of an embodiment of the display system 58 where the display system 58 includes the double mirrored display system 250. In the depicted embodiment, the user's eye 270 is shown with the pupil 272 looking in a forward direction 274 away from the head (e.g., direction such that when both eyes are looking in the forward direction the corresponding vectors 274 for each eye are parallel to each other and to a plane that extends between and separates the frontal sinuses, bisecting the nose). When looking in the forward direction 274, the eye may not see information from the display system 250 and/or the display system 250 itself. Indeed, the user may look straight ahead during performance of the activities 22, 24, 26, 28, and/or 30 and have an unobstructed view. When the user then decides to receive information, such as information 130, 134 provided by the double mirrored display system 250, the user may glance to a side so that the pupil 272 moves from the forward direction 274 towards a position 276. That is, when the user moves the pupil 272 a certain angle α away from the forward direction 274 and towards the double mirrored display system 250, the user may now see information presented by the double mirrored display system 250. For example, at position 276, the pupil may enter the eye box 278 so that the light projected via the double mirrored display system 250 is now visible. In certain embodiments, the angle α may be between 10° to 90°.

FIG. 10 illustrates a schematic top view of an embodiment of the display system 58 where the display system 58 includes a single mirrored display system 280. In the depicted embodiment, the user's eye 270 is shown with the pupil 272 looking in the forward direction 274 away from the head. As mentioned above, when looking in the forward direction 276, the pupil 272 may not see information provided via the single mirrored display system 280 or the single mirrored display system 280 itself

As illustrated, the projective display system 256 may project information, such as information 130, 134, via light. The light may reflect off of a mirror 282, and then be further modified via optics 284, which may include a lens or lenses, including correcting lens or lenses, aspheric lens or lenses, or a combination thereof. The single mirrored display system 280 may include a light travel length or track length longer than directly projecting the light into the eye 270, but shorter than the light travel length of the double mirrored display system 250. The user may look straight ahead, e.g., in the forward direction 274, during performance of the activities 22, 24, 26, 28, and/or 30 and have an unobstructed view. When the user then decides to receive information, such as information 130, 134 provided by the single mirrored display system 280, the user may glance to a side so that the pupil 272 moves from the forward direction 274 towards a position 276. That is, when the user moves the pupil 272 a certain angle α away from the forward direction 274 and towards the single mirrored display system 280, the user may now see information presented by the single mirrored display system 280. For example, at position 276, the pupil may be able to see inside of the eye box 278 so that the light projected via the single mirrored display system 280 is now visible. In certain embodiments, the angle α may be between 10° to 90°.

FIG. 11 illustrates a schematic top view of an embodiment of the display system 58 where the display system 58 includes a direct optical display system 290. In the depicted embodiment, the user's eye 270 is shown with the pupil 272 looking in the forward direction 274 away from the head. As mentioned above, when looking in the forward direction 276, the pupil 272 may not see information provided via the direct optical display system 290 or the direct optical display system 290 itself

As illustrated, the projective display system 256 may project information, such as information 130, 134, via light. The light may then be further modified via optics 292, which may include a lens or lenses, including correcting lens or lenses, aspheric lens or lenses, or a combination thereof. The direct optical display system 290 may include a light travel length shorter than the light travel length of the double mirrored display system 250. The user may look straight ahead, e.g., in the forward direction 274, during performance of the activities 22, 24, 26, 28, and/or 30 and have an unobstructed view. When the user then decides to receive information, such as information 130, 134 provided by the direct optical display system 290, the user may glance to a side so that the pupil 272 moves from the forward direction 274 towards a position 276. That is, when the user moves the pupil 272 a certain angle α away from the forward direction 274 and towards the direct optical display system 290, the user may now see information presented by the direct optical display system 290. For example, at position 276, the pupil may be able to see inside of the eye box 278 so that the light projected via the direct optical display system 290 is now visible. In certain embodiments, the angle α may be between 10° to 90°.

FIG. 12 illustrates a schematic top view of an embodiment of the display system 58 where the display system 58 includes a direct display system 300. In the depicted embodiment, the user's eye 270 is shown with the pupil 272 looking in the forward direction 274 away from the head. As mentioned above, when looking in the forward direction 276, the pupil 272 may not see information provided via the direct display system 300 or the direct display system 300 itself

As illustrated, the projective display system 256 may project information, such as information 130, 134, via light. The light may then be further modified via microlens or light-field projection optics 302. The microlens(es) may include diameters less than a millimeter, and may include gradient-index (GRIN) lenses, micro-Fresnel lenses, binary-optic lenses, and so on. The light-field projection optics may include lenslet arrays, projective arrays, and so on. The direct display system 300 may include a light travel length shorter than the light travel length of the double mirrored display system 250. The user may look straight ahead, e.g., in the forward direction 274, during performance of the activities 22, 24, 26, 28, and/or 30 and have an unobstructed view. When the user then decides to receive information, such as information 130, 134 provided by the direct display system 300, the user may glance to a side so that the pupil 272 moves from the forward direction 274 towards a position 276. That is, when the user moves the pupil 272 a certain angle α away from the forward direction 274 and towards the direct display system 300, the user may now see information presented by the direct display system 300. For example, at position 276, the pupil may be able to see inside of the eye box 278 so that the light projected via the direct display system 300 is now visible. In certain embodiments, the angle α may be between 10° to 90°.

It is to be understood that while the various display systems, e.g., systems 58, 250, 280, 290, 300 are shown as disposed on a side of a lens (e.g., side of lens of swim goggles 14, sunglasses 16, ski goggles 18, visor 20) in the figures above, the various display systems, e.g., systems 58, 250, 280, 290, 300 may be disposed on top/bottom of lenses or in other portions of the swim goggles 14, sunglasses 16, ski goggles 18, and/or visor 20 that are visible when placed over the eyes. Accordingly, the angle α away from the forward direction 274 may point towards any portion of the swim goggles 14, sunglasses 16, ski goggles 18, and/or visor 20, including lens portions, that are visible by moving the pupil 272 away from the forward direction 274.

Technical effects of the invention include providing for a minimally intrusive display system that may be disposed in a variety of eyewear to provide for feedback during certain activities, including sports activities. The minimally intrusive display system may derive certain metrics and performance measures during performance on an activity, and then display the metrics and performance measures to a wearer of the eyewear. Haptic and audio feedback may also via provided via the minimally intrusive display system.

This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art.
